During WWI, the Admiralty was concerned about supplies of magnetos for aero-engines for the Royal Naval Air Service. They encouraged several British companies to develop magnetos including Morris and Lister of Carlton Works, Lockhurst Lane, Coventry. They became the ML Magneto Syndicate Ltd. and produced all types of magnetos for 4 and 6 cylinder cars, light cars, motor cycles and aeroplanes. One of their more innovative designs used for motorcycles was called the Maglita and was described as ‘a combined direct current generator and inductor magneto’.
